It would have been better if they had given them a sandwich rather than plain bread. The butter etc would probably have reduced the glucose spike somewhat, which is what the fats and nuts in the bar probably did. Not the most scientific of tests

I can think of a lot of things that could have been changed to mitigate the results. But then they wouldn't have answered the question of whether bread raises blood glucose more than a candy bar or not.
